Geelong Grammar School - In 1966, Prince Charles traveled to Australia to spend two terms at the Timbertop campus of Geelong Grammar School in Victoria. He's pictured here meeting locals in North Bondi, New South Wales, shortly after arriving in the country.

Meeting the locals - While at Timbertop, Charles would stay at Devon Farm, Lilydale, where he befriended four sisters, Jane (10), six-year-old Amanda, Penny who was four, and three-year-old Lisa. Pictured: the siblings with the then 17-year-old prince.

Reminiscing - During a royal tour of Australia in April 2018, Charles and Camilla visited Lilydale, where the prince was reunited with the now grown-up sisters. They presented him with a framed photograph of their youthful get-together 52 years earlier. Reminiscing, it was smiles and laughter all round.

Death of Diana - Left to right: Earl Spencer (Diana's brother), Prince William, Prince Harry, and the Prince of Wales, waiting as the hearse carrying the coffin of Diana, Princess of Wales prepares to leave Westminster Abbey, following her funeral service.

Grandchildren - The documentary about Prince Charles, 'Charles at 70,' revealed the close bond he has forged with his grandchildren from William and Harry: Prince George, Princess Charlotte, Prince Louis, and latterly, Prince Archie.

On the beach at Brisbane - In April 2018, the royal couple were back down under on a tour that included a visit to the Commonwealth Hub at Broadbeach to unveil the final plaque on the Commonwealth Walkway at Gold Coast, near Brisbane.

HRH Prince Charles: a life in pictures

The heir apparent turns 71 on November 14

Charles, Prince of Wales is the heir to the British throne. The eldest son of Queen Elizabeth II and Philip, Duke of Edinburgh, His Royal Highness is also father to princes William and Harry—and is the oldest and longest-serving heir apparent in British history!

Charles has spent his life under public scrutiny, a fact the prince has not always been comfortable with. Yet he remains a hugely popular member of the royal family, and one of its hardest working! Now in his seventies, Prince Charles continues to carry out his royal duties, often accompanied by his wife, Camilla, Duchess of Cornwall.
